where one solid is surrounded by another solid.
I am solving heat conduction equation in each solid, so each solid has its own specific heat (c), density and thermal conductivity (k), thus we will solve two coupled time dependent temperature equations. Does laplacianFoam will handle two regions? How about chtMultiRegionFoam. any hint will be great? Last edited by jr33; February 11, 2013 at 13:00. |

Hi Reno,
Pure heat conduction in solid: laplacianFOAM attaching of two regions depends on which software you are using for meshing |

Thanks Omkar for comments.

If you understand the chtMultiRegionSimpleFoam/multiRegionHeater tutorial you willbe able to set up your case.

Thanks for comment, by now, I have figured the details of multiRegionHeater.
Currently I am stuck at meshing part: I mean: How to define interface between two regions? I use gmsh for meshing, I dont have blockMeshdict file. |

An alternate method is to use elasticThermalSolidFoam in the solidMechanics branch of OpenFOAM-1.6-ext. This solver allows for different properties in different regions, check out the bimaterialCase tutorial case for elasticSolidFoam. elasticThermalSolidFoam solves the energy equation for temperature and then the momentum equation for displacements, obviously you could comment out all the displacement/stress stuff. One advantage of this method is you just need one mesh with one region and no need to define an interface. Just an option, Best, Philip |

Thanks Philip, I downloaded the 1.6 extend version of openfoam from here: http://www.cfd-online.com/Forums/ope...t-problem.html
I did nt see " elasticSolidFoam" case or "solidMechanics" branch, is anyway I can find correct files. Last edited by jr33; February 12, 2013 at 17:55. |

The solidMechanics code is a git branch on the OpenFOAM-1.6-ext git repository.
As the git repository is currently down, I have put ".tgz" of the solidMechanics solvers here. I usually put the solidMechanics directory in the $FOAM_SOLVERS directory. Best, Philip |
